Christie’s sells rare blue diamond for over $40m USD

The 17.61 carat, pear-shaped Bleu Royal diamond, set in a ring, fetched $43.8 million, they said.

It is the “largest internally flawless fancy vivid blue gem” ever to appear for sale in auction history, Christie’s said.

Part of a private collection for 50 years, it was the first time the Bleu Royal was sold at an auction.

“This diamond is amongst the rarest to have been unearthed,” the auction house said in a statement.

Christie’s said only three fancy vivid blue diamonds over 10 carats had appeared for sale in its 250-year auction history, in 2010, 2014 and 2016.

Rare blue diamond sells for USD $44 million at Christie’s

Christie’s has auctioned one of the rarest blue diamonds in the world for a staggering $44 million.

On Tuesday, the stone called the “Bleu Royal” went under the hammer as one of the highlights of the auction house’s Luxury Week sale in Geneva, far outstripping the presale estimate. It is the first time the stone has been sold at auction, having been in private hands for the past half century.

Set into a ring, the 17.61 carat, pear shaped diamond is considered the largest internally flawless vivid blue diamond to have ever come to auction, and had a presale estimate of $35 million. At the sale, it eventually realised $43.8 million, making it the most expensive jewel sold at auction this year.

4.83 ct Fancy Blue Diamond Sells for $8.8 million USD

A 4.83 carat fancy vivid blue diamond ring sold for $8.8m at Christie’s Hong Kong as the Magnificent Jewels sale brought in a total of almost $60m.

The brilliant cut IF Type IIb gem (pictured) was surrounded by fancy-cut diamonds, in a gold setting. It sold between the low and high estimates of $7m to $10.2m.

The blue diamond led the sale, followed by two items which both sold for above their high estimates.

An octagonal step-cut 21.38 carat sapphire in a platinum ring set with tapered baguette cut diamonds sold for $4.5m (high estimate $2.3m).

And an 8.92 carats fancy vivid yellow orange pear modified brilliant cut diamond, in a platinum and gold ring, with pear brilliant-cut diamonds of 1.12 and 1.11 carat, sold for $4m (high estimate $3.8m).

Ultra-rare Bulgari Laguna Blu diamond sells for $25 million

A rare,11.16-carat fancy vivid blue diamond named the “Bulgari Laguna Blu” has fetched slightly more than $25 million at a Sotheby’s Magnificent Jewels sale in Geneva.

The auction house brought the clock back to pre-pandemic times by achieving the best performance since May 2018, with total proceeds of over 76 million Swiss francs (about $85m).

Sotheby’s noted the exceptional blue diamond was put up for auction last and after a four-minute bidding battle between three telephone bidders and one bidder in the room, it eventually found a buyer on the phone.

The sale made of the Bulgari Laguna Blu the most expensive jewel ever sold in Geneva. It is also the largest blue diamond in a Bulgari jewel and the brand’s most valuable gem to ever be put up for sale.

The Bulgari Laguna Blu is a rarity three times over, as it is a blue diamond, a jewel signed by Bulgari, and an unseen and unmodified gemstone.

Bulgari’s global Ambassador, actress Priyanka Chopra, wore the Bulgari Laguna Blu this year’s Met Gala in New York.

The Italian jewelry maker set the oceanic-blue sparkler in a bespoke diamond necklace for actress Priyanka Chopra Jonas, and the stone then was removed and remounted onto a ring—similar to the house’s original 1970s design.

The diamond was initially mounted as a ring by Bulgari for a special commission by the original owner. It was sold in 1970 and it’s now part of a necklace.

De Beers Cullinan Blue Diamond Could Bring $48M at Auction

Sotheby’s will auction a stone described as “the largest vivid blue diamond ever to appear at auction” on April 27 in Hong Kong.

Sotheby’s estimates that it could bring $48 million.

The 15.1 carat step-cut blue was cut from a rough stone discovered in April 2021. It is “the largest internally flawless step cut vivid blue diamond that the Gemological Institute of America (GIA) has ever graded,” according to a press statement.

“This diamond ranks as one of the best De Beers has ever seen,” said Bruce Cleaver, CEO of De Beers Group. “It is extremely rare and unique, and as the Home of Diamonds, De Beers is pleased to join together with Sotheby’s to bring this diamond to the world.”

Only five blue diamonds over 10 carats have ever come to auction, Sotheby’s notes. Until now, none has exceeded 15 carats.

“Blue diamonds of any kind are rare on the market, but this is the rarest of the rare; nothing of remotely similar calibre has appeared at auction in recent years,” says Patti Wong, chairwoman of Sotheby’s Asia. “Hundreds of millions of years in the making, this extraordinary blue diamond is surely one of nature’s finest creations.”

The diamond comes from the Cullinan mine in South Africa.

A blue diamond ring is among the top lots at the Sotheby’s Magnificent Jewels sale in New York next month.
The piece contains a cut-cornered rectangular modified brilliant-cut, 6.11-carat, fancy-intense-blue, VS2-clarity diamond surrounded by round diamonds. It is estimated to bring in up to $6.5 million at the December 7 auction, Sotheby’s said Monday.

Sotheby’s is collaborating with Brilliant & Black designer Lauren Harwell Godfrey to make a finished jewelry piece for the diamond, it noted. She has created two original designs that utilize her signature triangle inlay pattern — for a necklace and a ring.

Meanwhile, 30 jewels from an American private collector will also go under the hammer. The entire group is estimated at more than $6 million and includes one of the most significant collections of Bulgari pieces ever to come to market, Sotheby’s explained.

In total, the auction house will offer more than 200 lots, with the sale forecast to fetch as much as $70.1 million — the highest estimate for a New York Magnificent Jewels sale since December 2018, Sotheby’s added.
